Saturday, May 7, 2022, 1:37 pm – Thunderstorm season will begin for the prairies this weekend, including a serious risk with a non-zero tornado chance for some, but it will only be a brief taste as winter returns with cooler temperatures and wetter waves for Alberta until Sunday night.
The prairies got a well-deserved idea of summer time this week, but the heat is about to leave as much cooler air sets in and temperatures drop in the coming days. Earlier, the eastern prairies will see a threat of severe weather on Saturday, including a very conditional chance of spinning storms, as thunderstorm season begins with a brief overview. Mother’s Day can also cause storms to break out, only to be followed by wet waves in Alberta as temperatures drop. More about storm threats and what else to expect this weekend, below.

SATURDAY: CONTINUING HEAT DEDICATED BY HEAVY STORM FROM STORM, CONDITIONAL RISK FOR RUNNING STORMS
There is only one warning of a severe thunderstorm in southeastern Manitoba this year, which occurred on April 23 – in fact the only one issued in Canada so far. But that is likely to change, as there is a risk of strong thunderstorms on Saturday.
A serious weather threat is posed in southeastern Saskatchewan and southwestern Manitoba in the afternoon and evening. Clocks for severe thunderstorms have been issued for the above-mentioned regions. The recent intense warming has increased our energy during a thunderstorm to lead to potentially stronger storms and more hail, but the threat doesn’t stop there.
The center of the lowlands has shifted north and west, extracting regions at risk of severe thunderstorms.
The dynamics of strong winds up and to the surface may also support the threat of supercells in extreme southeastern Saskatchewan and southwestern Manitoba. Areas from Wynyard and Estevan, Sask., To Melita and Winkler, Man., Will be targeted in the early evening for this risk.
People in these regions must plan to stay indoors, as there is a non-zero threat of tornadoes. However, this is a very conditional chance that it all depends on the time of development of the storm.
Other possible dangers in any storm that becomes severe will be strong gusts of wind and heavy hail. Meanwhile, the general threat of minor storms will extend from southern Alberta to northern Saskatchewan and Manitoba.
On Saturday, the cooling will reach Saskatchewan, with temperatures dropping to mid-teens, while continued heat remains in southern Manitoba, where daily highs remain in the low 20s.
SUNDAY AND OUTSIDE: STORM RISK REDUCTION, SNOW RETURN?
Adhering to the reality for Alberta in the spring so far, we are talking about the risk of thunderstorms in the southern areas this weekend, with snow at the foot and north of Alberta.
On Mother’s Day, the threat of a thunderstorm will remain in effect on Sunday in the southern prairies, although all that develop must remain under strict criteria. They could still bring a little hail and strong gusts of wind.
However, on Sunday night against Monday, these thunderstorms in southern Alberta will be replaced by wet waves as temperatures drop.
Much cooler weather will continue on the western prairies early next week. Temperatures will return to near-seasonal mid and weekend. Meanwhile, the eastern parts of the region will remain within a few degrees of the season.
Also, an outstanding model is returning to Manitoba and eastern Saskatchewan. Another low level in Colorado will bring massive rains on Monday.
Unfortunately, this has the potential to bring 20-40 + mm to areas that are still recovering from floods and wetlands, missing areas where rain is desperately needed.
Forecasters are also monitoring the potential for another powerful storm at the end of next week and weekend. There is a chance that this system will take a more westerly direction. If this is confirmed, then it will lead to rain in areas that really need it.
LOOK AHEAD: SUMMER TASTE MAY BE A JOKE
This sample of summer heat is not long for the world. Make sure you go out and enjoy it while it lasts, because it looks like the model will start to turn to the cooler side of the season in the middle of the month.
“Our forecast for mid and late May requires temperatures to be close to or slightly lower than normal in most of Canada,” Dr. Doug Gillam said in his exclusive May forecast for The Weather Network.
Not everything is bad news, he added.
“Although the map is very blue, we do not expect temperatures to be far from seasonal in these regions. Also, keep in mind that the “seasonal” is constantly increasing during the month. Even the cool May will include many days of pleasant spring weather. ”
